beta decay. Beta decay happens inside the nucleus and is the change of a neutron into a proton and an electron. The electromagnetic force acts between electrically charged particles. This force entails that particles with opposite charges attract‚ while like charges repel. The electromagnetic force has an infinite range and involves the exchange of photons. According to quantum electrodynamics‚ photons work on both the microscopic and macroscopic

Concepts 1. Electricity is the flow of electric charge (electrons). 2. Electric Charge is a property of subatomic particles. 3. Current is the movement of electric charge. 4. Voltage is the electric potential that exists to move a charge. 5. Power is the rate at which electric energy is flowing in a circuit. 6. Ohm’s Law: Power = Voltage x Current. 7. Resistance is a physical property that quantifies how well a charge can move through a material. 8. Ohm’s Law: Voltage

Class X‚ PHYSICS‚ "Electricity" Definitions 1. Insulators Those material objects that do not allow charge to pass through them are known as Insulators or non-conductors. 2. Conductors Those material objects that allow the charge to pass through them are called conductors. 3. Semi Conductors Those material objects that allow some charge to pass through them are called Semi-Conductors. 4. Free Electron Those electrons that are loosely bound by their atom and can move freely

What might you conclude with your observations? The cup and the fur have opposite charges. 3. The forces between charged objects are called electric forces. When a charged object is brought close to the hanging cup‚ the cup is acted on by three forces: gravitational force pulling down‚ the string tension pulling up along the string‚
